The vegetative nerves, also known as the autonomic nerves in medicine (all autonomic nerves below refer to the vegetative nerves), are the nervous system in the body that controls the voluntary behavior of the body. In terms of its distribution and function, the autonomic nerves are mainly located in the internal organs, cardiovascular and glandular bodies of the body and have a strong control and regulatory capacity. In the human body, the autonomic nerves are mainly responsible for tension and relaxation, work and rest, and implement their collective regulation and control mainly through two divisions, one is the sympathetic nervous system and the other is the parasympathetic nervous system, both of which are balanced by mutual constraints. The autonomic behavior it controls is mainly to ensure human survival, including blood pressure, heart rate, sweating and food digestion, but also to control the “stress” and “emergency” responses of the human body in emergency situations. In contrast to the nerves that govern the fine movements of the hands and feet, the autonomic nerves govern the activities of organs that are not under the control of the human consciousness, such as heartbeat and respiration. Therefore, the autonomic nerves are an important part of the human body, regulating the most basic physiological activities of the body, maintaining the balance of the human cellular environment and cooperating with the whole body somatic nerve activities.
